Definitions

  • Torque converters are commonly used to transmit torque from an engine to a transmission in an automobile.
  • a typical torque converter generally includes three main components, an impeller, a turbine and a stator all disposed within a torque converter housing.
  • the torque converter housing is usually filled with hydraulic fluid.
  • the stator or a wheel stator assembly is functionally disposed between the impeller and the turbine.
  • the wheel stator assembly includes a ring-shaped stator carrier, a plurality of stator blades provided on an outer circumferential surface of the stator carrier, an outer race fixed to the stator carrier at its inner circumferential portion, an inner race placed close to an inner circumferential portion of the outer race and a one-way clutch placed between the inner and outer races.
  • the stator assembly engages a stator shaft fixed to the transmission so as not to rotate relative to the transmission.
  • an outer race member with a plurality of cirumferentially inclined surfaces and a plurality of concave portions, one concave portion formed between each pair of adjacent inclined surfaces;
  • stator carrier 21 Sides of the outer race 23 and the inner race 24 on the right of FIG. 1 are supported by a receptacle 21a defined the stator carrier 21.
  • the receptacle 21a of the stator carrier 21 is supported by the impeller hub 5c via a thrust bearing 16. Ends of the outer race 23 and the inner race 24 on the left of FIG. 1, respectively, contact the retainer 25, and the retainer 25 is supported by the turbine hub 8 via a thrust bearing 17.
  • the stator 7 is retained in position in axial directions between the impeller hub 5c and the turbine hub 8 by the thrust bearings 16 and 17.
